Locations of loudspeakers were examined utilizing Frequency dependent interaural cross correlation (FIACC) for optimum sound field recomposition in multichannel recording and reproducing process. Experiments were conducted by comparing pairs of FIACC, where one of a pair was measured in an original sound field and the other was measured in the reproduced sound field. Conclusively, it became clear that ITU's recommendation to the speaker arrangement in 5 channel system is reasonable.
